Summary
Brief summary (as posted)
This multicenter, retrospective and prospective observational, cohort study will examine the effect of second-line Tarceva treatment on long response in non-small cell lung cancer (NSCLC) participants with wild type or unknown EGFR status. Participants will be observed from the start of treatment for 8 months or until death. The extension of the retrospective versus prospective observation will depend on the lag between the date of the participant enrollment and the date of beginning of erlotinib therapy.

Arms and outcomes
Arms (1)
- label
- NSCLC Participants
- description
- Participants with advanced non-small cell lung cancer (NSCLC), treated in second-line with erlotinib, presenting wild-type, not tested or unknown Epidermal Growth Factor Receptor (EGFR) status, and with stable disease at the first revaluation after start of erlotinib therapy.
Primary outcomes (2)
- measure
- Percentage of Participants With Stable Disease (SD) or Objective Response (Complete and Partial Response [CR + PR] According to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
- timeFrame
- Up to 8 months
- description
- SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study. Objective response was defined as having a CR or PR. CR was defined as disappearance of all target and non-target lesions and no new lesions, and all pathological lymph nodes must have decreased to \<10 millimeters (mm) in short axis. PR was defined as at least a 30% decrease in the sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesions, and no new lesions. PD was defined as at least a 20% increase in the sum of diameters of target lesions compared to the smallest sum of diameters on-study and an absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions.
